Cropmark
|
Cropmarks appear as light and dark marks in growing and ripening crops. These marks relate to differences in the soil below. For example, parched lines of grass may indicate stone walls. Crops that grow over stone features often ripen more quickly and are shorter than the surrounding crop. This is because there is less moisture in the soil where the wall lies.

Aerial Photograph
|
Aerial photographs are taken during an aerial survey, which involves looking at the ground from above. It is usually easier to see cropmarks and earthworks when they are viewed from above. Aerial photographs help archaeologists to record what they see and to identify new sites. There are two kinds of aerial photographs; oblique and vertical.

Roman

About 43 AD to 409 AD (the 1st century AD to the 5th century AD)
The Roman period comes after the Iron Age and before the Saxon period.
The Roman period in Britain began in 43 AD when a Roman commander called Aulus Plautius invaded the south coast, near Kent. There were a series of skirmishes with the native Britons, who were defeated. In the months that followed, more Roman troops arrived and slowly moved westwards and northwards.
